squiggy, You will need the Line 6 Workbench. So If you have the Line 6 Workbench, you will hook it up to your guitar and computer and make sure it's operational. Next, on your computer you will Locate the Line 6 Monkey app. and throw it in the trash. next you will go to the line 6 Website and go to downloads, select Line 6 Monkey and download it, next you will open the Line 6 monkey app., next you will click OK and an update window will open. on the list you will see "flash memory" which you will highlight and then over to the right you will click "update selection" this procedure will take a while, and should perform the factory reset. I use a mac , so if you have a pc, your updates window might be or look a little different. I perform this reset every so often. The variax memory chip seems to be prone to data corruption. So this is why we need to make this fix now and then. I just performed this reset before sending this reply, and it's like a breath of fresh air, However I do keep a backup of my presets on my computer drive and on CD. I hope I didn't hypnotize you with (next you will do this and next you will do that). Trying to contact the technocrats at LIne 6 is often hard or even next to impossible to do, I think they might be asleep at the wheel. I hope this will lead to a favorable outcome for you.
